Definitions
- the present invention relates to a lubricating oil composition, and a precision reduction gear using the same.
- a lubricating oil composition for use for reduction gears of various industrial machines is required to have wear resistance for preventing wear of gears, etc.
- a method for improving wear resistance of a lubricating oil in general, there are known a method of adding a phosphorus-sulfur-containing compound and a sulfur-containing compound to a lubricating oil (for example, see PTL 1), a method of adding a sulfur-based compound, an organic molybdenum-based compound and a phosphorus-containing compound (for example, see PTL 2), etc.
- a method for reducing a friction coefficient in general, there is known a method of adding an organic molybdenum-based compound (for example, see PTL 3).
- precision reduction gears are incorporated in joint sites and the like of industrial robots.
- Such precision reduction gears use a specific gear such as a planetary gear for realizing a large reduction ratio in a limited space, and the gear ratio of engaging gears (number of rack gear teeth/number of pinion gear teeth) therein is extremely large.
- industrial robots repeat switchover of reciprocating motion and motion speed. Accordingly, precision reduction gears for industrial robots are given an extremely larger load than that to general reduction gears. Consequently, an oil film is difficult to form in the lubrication state, therefore often resulting in boundary lubrication or mixed lubrication in many cases, and causing wear with ease to form wear debris.
- a conventional lubricating oil heretofore used in reduction gears of various industrial machines could not still attain sufficient wear resistance even though the above-mentioned compounds are added thereto.
